Dongying Haihe Machinery Co.,Ltd here,manufacturing & exporting all kinds of precision casting product for more than 23 years
Produce:produce stainless steel castings, carbon steel casting and alloy casting.
Product: flanges,valves,cylinders,actuators,tube fittings,manifolds,marine hardware, construction hardware, house hardware, automobile part, motorcycle part, hinge, devices for hydraulic press and for oil extraction, cross fitting, golf head and so on.
Foundry technology: investment castings, lost wax castings & precision castings.And both sodium silicate and silica sol processed have been adopted.
Casting technology & other capabilities:
Investment castingalso can be called " precise casting " or " lost wax casting " or " de-waxing casting ". The casting materials can widely be used, and no limitation for product shape as well as complex structure.The most important characteristic of investment casting is the closer tolerance control, fewer or no machining allowance, and better surface finish. In the casting industry, the investment casting can be used instead of other casting methods, so as to reduce machining allowance and the cost, improve the dimensional precision and surface finish, so as to meet the requirements of a higher level product.

Besides investment casting in sodium silicate and silica sol technology, some other capabilities are as follows:
1. Rough and precision machining
CNC and machine tools could feed your machining requirements.
2. Mould design
Strong mould-making capabilities aided by advanced CNC machining centers, sometimes CAD files can be directly used for rapid tooling by CAM technique, precious time is saved.
3. Polish
We have the strongest process of polishing contained grinding, polishing and electric-polishing.
